DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New diagnostic test can detect COVID-19 virus even when it mutates

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has developed a diagnostic test that can detect the virus that causes COVID-19 even after it has gone through mutations.

Arginine methylation important in SARS-CoV-2 viral replication

Researchers show that methylation of arginine in the virus nucleocapsid protein controls the protein's functions and plays a role in the life cycle of the SARS-CoV-2 virus.

GlyNAC could improve many age-associated defects in older humans

A pilot human clinical trial conducted by researchers at Baylor College of Medicine reveals that supplementation with GlyNAC - a combination of glycine and N-acetylcysteine as precursors of the natural antioxidant glutathione - could improve many age-associated defects in older humans to improve muscle strength and cognition, and promote healthy aging.

Advanced technology provides a fine-grained picture of lung pathology in COVID-19

A team led by investigators at Weill Cornell Medicine and NewYork-Presbyterian has used advanced technology and analytics to map, at single-cell resolution, the cellular landscape of diseased lung tissue in severe COVID-19 and other infectious lung diseases.

Diabetes drug appears to exploit vulnerability of AIDS-causing retrovirus HIV

A team led by scientists at the UNC School of Medicine discovered an important vulnerability of the AIDS-causing retrovirus HIV, and has shown in preclinical experiments that a widely used diabetes drug, metformin, seems able to exploit this vulnerability.

New modeling approach to better understand how tumors become aggressive

Although the development of secondary cancerous growths, called metastasis, is the primary cause of death in most cancers, the cellular changes that drive it are poorly understood.

Scientists use specially designed gold nanoparticles to 'seek out' bone stem cells

Researchers at the University of Southampton have developed a new way of using nanomaterials to identify and enrich skeletal stem cells - a discovery which could eventually lead to new treatments for major bone fractures and the repair of lost or damaged bone.

FDA acknowledged receipt of ORNL’s cancer-fighting Ac-225 isotope

A rare isotope in high demand for treating cancer is now more available to pharmaceutical companies developing and testing new drugs.

Novel molecule could offer a new way to fight against SARS coronavirus 2

Scientists at the University of Bonn and the caesar research center have isolated a molecule that might open new avenues in the fight against SARS coronavirus 2. The active ingredient binds to the spike protein that the virus uses to dock to the cells it infects.

Heidelberg researchers introduce a reproducible division mechanism for synthetic vesicles

One big challenge for the production of synthetic cells is that they must be able to divide to have offspring. In the journal Angewandte Chemie, a team from Heidelberg has now introduced a reproducible division mechanism for synthetic vesicles.

Research challenges perception that dingoes are virtually extinct in the wild

Almost all wild canines in Australia are genetically more than half dingo, a new study led by UNSW Sydney shows – suggesting that lethal measures to control ‘wild dog’ populations are primarily targeting dingoes.

High-fiber diet can significantly alter the gut microbiome and nutrient intake

A short-term intervention in daily fiber consumption can significantly alter the gut microbiome and nutrient intake, according to a study led by University of California, Irvine researchers. The research was recently published by the American Society for Microbiology.

AI study on aggressive form of cancer could improve patient outcomes

International genomics research led by the University of Leicester has used artificial intelligence (AI) to study an aggressive form of cancer, which could improve patient outcomes.

Size is the only difference between male and female brains, shows study

How different are men and women's brains? The question has been explored for decades, but a new study led by Rosalind Franklin University neuroscientist Lise Eliot is the first to coalesce this wide-ranging research into a single mega-synthesis. And the answer is: hardly at all.

DAPK3 slows tumor growth by activating fierce-sounding STING pathway

The glow of a panther's eyes in the darkness. The zig-zagging of a shark's dorsal fin above the water. Humans are always scanning the world for threats.

Scientists identify new genetic clues to treat “silent’ stroke

Scientists have identified new genetic clues in people who've had small and often apparently 'silent' strokes that are difficult to treat and a major cause of vascular dementia, according to research funded by the British Heart Foundation (BHF) and published in The Lancet Neurology.

Scientists describe the mechanisms that regulate embryonic stem cells

Scientists at the Proteomics Core Unit of the Spanish National Cancer Research Centre (CNIO), headed by Javier Muñoz, have described the mechanisms, unknown to date, involved in maintaining embryonic stem cells in the best possible state for their use in regenerative medicine.

Study identifies NCOA3 as a novel therapeutic target for melanoma

For the first time, activation of nuclear receptor coactivator 3 (NCOA3) has been shown to promote the development of melanoma through regulation of ultraviolet radiation (UVR) sensitivity, cell cycle progression and circumvention of the DNA damage response.
